more help

Hi all, Hoping to get some help with my furnace issue. It's a Weil-McLain HE-4, CP 1554462, natural gas hot water baseboard unit. It has a Hamilton Controls aquastat, a Fenwal 35-655600-003 control box and a RobertShaw gas valve. Problem: Very frequently the unit short cycles where ignitor will glow, gas valve opens, flame on for about 30 seconds, flame out; ignitor on, gas valve opens, flame on, flame out, and so on. Eventually, the gas valve doesn't open, but the ignitor still glows, and it goes into ignition lockout. The exhaust blower continues to run. I usually find out when the house temperature goes to the mid-60's. I also think the water isn't heating to 180 degrees. The temperature gauge is hard to read straight-on since it's behind the circulating pump, but it looks like it's getting up to 140. I've had the igniton control box and gas valve replaced earlier this winter. It seemed to help for about a month, then same problem. I even took a movie of it ([URL="www.codispoti.net/furnace.wmv"]click here - 56k warning, big file![/URL]) Please help! My regular furnace repair guy is out of town all week!

Our house is 3 years old. We have a Utica Boiler, uses oil. About a year and a half after we moved in we smelled oil burning in the house and soon found a light coat of soot in the house. Called for service, it became worse. They finally fixed, or so we thought (it was late spring anyway). Insurance company paid for cleanup and promptly dropped us. Now it has happened again, only worse. Again we called for service (we have had it serviced regualrly by this company). Now the company that services it says we should have had a chimney installed, that a vent wasn't enough so they are blaming the guy who installed the boiler. We are afraid to call insurance company, but I'm afraid that the clean up will be more than we could afford or do ourselves. My husband and I do not understand what this 'puff back' is or why it is happening. (apparently neither do the technicians that come out to service the boiler.) Is the boiler of poor quality? Should we replace it? Installing a chimney would be a big expense. Utica boiler has not responded to our questions. Any helpful advice would be greatly appeciated!!!! Sandy
